技术领域
本实用新型涉及一种半导体混合集成电路器件，尤其涉及一种高压大功率运算放大器。
背景技术
由于运算放大器多为工作电压较低，输出功率较小。因而，无法直接应用于某些工作电压较高，负载较重的环境。目前，大多数是通过普通运算放大器、扩流电路组合使用来实现电路功能，且需要外加晶体管散热片，占用空间大，组装繁琐。尤其在一些恶劣环境下，例如超高温、超低温、高湿度、强振动等，普通元件无法工作。
实用新型内容
本实用新型要解决的技术问题是提供一种将运算放大器、构成扩流电路的大功率晶体管和电阻全部集成在一起，占用空间小，方便使用，并且能保证良好的散热效果，可适用于-40℃～+85℃的工作环境的高压大功率运算放大器。
本实用新型涉及的高压大功率运算放大器，包括管壳，其特征是：在管壳上通过粘结膜粘接有陶瓷基片，在陶瓷基片上印制有金导带和厚膜电阻，在陶瓷基片上通过焊膏焊接有运算放大器表贴元件，在陶瓷基片上还粘接有大功率晶体管，所述的大功率晶体管和厚膜电阻构成扩流电路，位于陶瓷基片上各元件之间通过互连引线连接。
上述的高压大功率运算放大器，所述的互连引线为金丝。
本实用新型将运算放大器表贴元件、大功率晶体管和电阻全部集成在陶瓷基片上，占用空间小，方便使用，并且能保证良好的散热效果，可适用于-40℃～+85℃的工作环境。
